The range of electric bikes can vary, but most riders are able achieve around 40km per charge with a 36v 13ah battery. One of the main factors in determining how far you can travel on a single charge is how much assistance you provide. Obviously, the more pedaling you do, the less strain on the battery and the more range you’ll achieve. Keep in mind, ‘pedal-assist’ bikes have higher ratings and achieve more range than throttle-controlled bikes because the rider is required to pedal at all times.
Another factor that can have a big impact is terrain. If you live in a hilly area or have lots of steep inclines – expect less range from your e-bike. Larger riders or people carrying heavy loads can also expect reduced output.
Speed is another big factor. Above 30km/h wind resistance takes a large toll on range. You are likely to do twice the range at 25km/h than at 35km/h.
Battery capacity is measured in Watt Hours, as a rough guide 100 watt hours will give you 10km of riding. A 36v15ah battery gives you (36×15=) 540 Watt Hours, so you could expect around 54km of assisted range.
